What is the effect of surface treatment on performance of S355J2G1W steel plate for construction machinery

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important S355J2G1W steel plate for construction machinery heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, S355J2G1W steel plate for construction machinery produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, S355J2G1W steel plate for construction machinery steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.

We are one of the largest weathering steel stock keepers in China and even in the world. For most specs weathering steel materials, we can arrange delivery within 5 days. Meanwhile, our weathering steel price is competitive. And for weathering steel coils, we do slit, S355J2G1W steel plate for construction machinery plate cut and so on further processing. We can meet different size and shape needs of customers.

Large-thickness S355J2G1W steel plate for construction machinery, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. S355J2G1W steel plate for construction machinery, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).
